Phil - Don Quixote has nothing on you!
That's a lot of research to prove that:
- there were 12 stations at the oil sand oven where front and rear housings cores were produced. 6 International machines for front housings and 6 International machines for rear housings. So, that means 6 DIFFERENT core boxes for each housing (plus the spare core boxes up in the pattern storage area on the second floor. Not every core box was identical due to repairs and cosmetic changes made over the years. this same explanation applies to changes in the filter bowl set core area (only there were 24 individual inserts plus spares). Ditto for the cope and drag patterns where there were 3 of each (plus spares).
The flow off scar on the top rail is an addition to the patterns that I HAD MADE. There was a problem with gas accumulating at the top of the rail during mold fill. We added those pins to help the gas escape better.
anyone who thinks we added 10-20% nickel to gray cast iron isn't just silly.
